Abstract

A refrigeration device that has utilization side heat exchangers (20, 30, 40) of a plurality of systems and in which liquid-side connection piping (53, 54, 55) is consolidated into a single line by liquid lines of a plurality of systems. When 100% heat recovery heating operation is performed without using an outdoor heat exchanger (15), the flow of refrigerant in a refrigerant circuit (50) is stabilized even at low outdoor temperatures to prevent reduction in refrigeration ability. Further, in order to prevent also a stop of operation of the refrigeration device (1) by a malfunction, a liquid refrigerant inflow path (66) is connected to a heat source-side liquid pipe (62) of an outdoor unit (10), which is connected to a gathering liquid pipe (53) of the liquid-side connection piping (53, 54, 55), and to an inflow opening of a receiver (17), and an on-off valve (SV1) is provided in the liquid refrigerant inflow path (66).
